The first full moon of the summer is set to rise gracefully in the eastern sky Wednesday through Friday evenings and will appear a little plumper and brighter than normal.

The June “Strawberry Moon” is marginally considered a supermoon, according to NASA, the last in a series.

Supermoons are those full moons that pass the Earth near the closest point in their monthly orbit (known as perigee) and can appear up to 30 percent brighter and 14 percent bigger than full moons that pass at their greatest distance (known as apogee).

The Strawberry supermoon comes on the heels of the May 26 “Flower Moon” and April 26 “Pink Moon,” which were also deemed supermoons. Of the supermoon trio, the Flower Moon made the closest pass to the Earth, according to EarthSky. The Strawberry Moon ranks as the third-closest full moon.

Some say March’s “Worm Moon,” 2021′s fourth-closest full moon, was also a supermoon. Criteria for what makes a supermoon vary.

The June full moon was given the strawberry moniker because it occurs when the fruit typically ripens in the northeastern United States. NASA notes that the moon is also sometimes referred to as the “Rose Moon,” “Mead Moon” and “Honey Moon.”

Clear skies over the majority of the Lower 48 states will promote outstanding moon-viewing conditions Wednesday night.

Clouds will be a bit more numerous in the West, especially in the Rocky Mountains, but much of California, Oregon and Washington should have favorable skygazing conditions, except right along the coast. Clouds may obscure viewing some in parts of the Northern Plains and Upper Midwest due to scattered thunderstorms along a cold front.

Predicted cloud cover Wednesday night at 11 p.m. eastern from the NAM model. 

If you miss the full moon Wednesday night, it will also appear close to full Thursday night. Weather conditions are again predicted to be mostly clear along the East Coast, although clouds may cover much of the Upper Midwest and Plains.

On Thursday, the moon will rise at 8:59 p.m., 8:54 p.m. and 9:05 p.m. local time in Washington, Chicago and San Francisco, respectively. In Washington, it will reach its highest point at 1:39 a.m. Friday, just 24.6 degrees above the southern horizon. According to NASA, this is the lowest full moon of the year.

“On the summer solstice, the sun appears highest in the sky for the year,” NASA explains. “Full moons are opposite the sun, so a full moon near the summer solstice will be low in the sky.”

Friday offers one more chance to see the moon close to full, rising at 10 p.m., 9:55 p.m. and 10:05 p.m. in Washington, Chicago and San Francisco, respectively. Cloud cover will be more pervasive in the eastern United States, but clear skies should prevail in the western states.

While the moon will be almost fully illuminated Wednesday, Thursday and Friday nights, it will be only 100 percent illuminated or technically full at 2:40 p.m. eastern Thursday, when it won’t be visible.
